Because of technical restrictions, I need to encode files in base64 format before upload.
To do that, I use the upload event of the Kendo Upload Widget to make a FileReader object with an onload event on that reader to get a base64 string.
Problem: the async upload handler is called before the reader onload finish. It’s a normal behavior because the both object are async.
How can solve that ? Is there a better method ?
Thanks a lot
